I compiled the list, included a little information, but all in all, the decision on who would win is based on your own opinions. I included 10. The matchups you could get out of this are plentiful, so rather than post a bunch of a matchups, I'll simply post the competitors and leave it up to you guys to make your own matchups and chime in on who you think is... The Deadliest Warrior.
Also keep in mind, these are not in-game battles. This is in a real world (real Nirn) scenario, so every little quality and trait plays huge roles in each matchup.

Dremora (Valkynaz): Intelligence, high quality weaponry, daedric armor. Shield spells and fire damage. Resistances to magic. Large physique. (Warrior type)
